ClearPixUpscale a screenshot to a sharp, readable size
Screenshots are fixed-size bitmaps: enlarging them normally just softens the text and UI edges. ClearPix runs Real-ESRGAN super-resolution to rebuild those edges at 2× or 4×, which helps when a capture has to go into a slide, a print or a high-DPI display. It is free, needs no sign-up and runs entirely in the browser, so internal screens and chat captures are never uploaded.
A screenshot captured on a laptop or phone often has to fill a projector, a printed handout or a 4K display. Plain resizing blurs the interface; AI super-resolution predicts clean edges so text and icons stay crisp at the larger size.

What is AI super-resolution?
Real-ESRGAN is a neural network trained on real-world image degradation. Unlike a simple resize, it reconstructs plausible high-frequency detail — sharper edges, recovered texture, cleaned-up compression artifacts. ClearPix runs the model in overlapping tiles on your own GPU (WebGPU) or CPU (WebAssembly), so even large images process safely without any server.
When to use 2× vs 4×
- 4×— small thumbnails, compressed social-media saves, AI-art drafts.
- 2×— moderate enlargements where you want a natural, less sharpened look.
- For very large sources, downsize first and let the model rebuild the detail.
Only process images you own or have explicit permission to modify.
How it works
Upload the screenshot
PNG is best for interface text; JPG and WebP work too. Files up to 2048 px on the longest side are accepted (1400 px without WebGPU).
Choose 2× or 4×
2× is usually enough for slides and documents. Use 4× for a small phone capture that must fill a large screen.
Download the enlarged PNG
The export keeps the screenshot’s sharp edges and flat UI colors. If the text was already illegible, upscaling cannot recreate the missing characters.
Your file never leaves your device. All AI processing runs locally in your browser on your own hardware — there is no upload, no queue, and no copy stored on any server. You can disconnect from the internet after the page loads and everything still works.
